VTE provides learners with the ability to better visualize the simulation models by interacting with a library of movies, 3D visualizations, diagrams, and DCS screens. For the operator, the ability to troubleshoot the process relies on understanding the flow and control of the unit. The 3D visualizations and movies allow the operator to better understand the process by seeing the configuration of equipment and instrumentation. Piping and Instrumentation Diagrams and DCS screens are representations of the unit that communicate important information to the operator.
